简要总结
Background Many nurses must shoulder heavy workloads and often develop depressive emotions due to work stress. Previous studies pointed out that binaural beat technology (BBT) and rhythmical photic stimulation can effectively improve negative emotions but there are very few related empirical studies.
Objectives This study examined the effectiveness of BBT combined with rhythmical photic stimulation in improving depressive symptoms in nurses.
Methods This is a randomized controlled trial and nurses in central Taiwan were recruited as participants. These participants were randomized into three groups: BBT combined with rhythmical photic stimulation group, BBT group, and relaxing music group. The intervention period was 2 weeks, with 30 minutes per session. The Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), vitality and mental health scale (VT&MH from SF-36), and heart rate variability (HRV) were used as parameters for pre- and posttest evaluation in this study. The Wilcoxon signed-rank test was used to test if there are significant differences in various parameters in the three groups before and after intervention. The Krusal-Wallis test was used to test for significant differences in parameter changes between the three groups.

结局指标
主要结局
Beck Depression Inventory-II (BDI)
时间窗: On Day 14 of the intervention, the researchers conducted the posttest (second test) at the participants' homes and the test content was the same as the first test. It took about 10 minutes.
There were 21 questions in the BDI, and a self-rated method was used for participants to fill in their thoughts in the last 2 weeks. A 4-point Likert scale was used. The score range of each question was 0-3 points. A total score of 0-12 points was normal, 14-19 points was mild depression, 20-28 points was moderate depression, and 29-63 points was severe depression.
HRV analyzer
时间窗: On Day 14 of the intervention, the researchers conducted the posttest (second test) at the participants' homes and the test content was the same as the first test. It took about 5 minutes.
HRV was used to measure heart rate variability, including five markers: (1) Mean heart rate; (2) SDNN: Standard deviation of all RR intervals, represent the physiological health of autonomic nervous system; the higher the SDNN, the better the physiological health of the autonomic nervous system; (3) nLF: Normalized low frequency, reflects sympathetic nervous activity. The higher the value, the greater the activity; (4) nHF: Normalized high frequency, reflects parasympathetic nervous activity. The higher the value, the greater the activity; (5) LF/HF, a marker reflecting sympathetic and parasympathetic nervous activity.
Pittsburgh Sleep Quality Index (PSQI)
时间窗: On Day 14 of the intervention, the researchers conducted the posttest (second test) at the participants' homes and the test content was the same as the first test. It took about 10 minutes.
There were 18 questions in the PSQI, and participants used a self-rated method to fill in their sleep quality in the last month on a 4-point Likert scale. The total score range was 0-21 points. The higher the score, the poorer the sleep quality. This scale has seven dimensions, including: (1) Subjective sleep quality; (2) Sleep latency; (3) Sleep duration; (4) Sleep efficiency; (5) Sleep disturbances; (6) Daytime dysfunction; and (7) Use of sleep medication. PSQI had good validity and reliability(Tsai et al., 2005).
次要结局
- Vitality scales (VT)(On Day 14 of the intervention, the researchers conducted the posttest (second test) at the participants' homes and the test content was the same as the first test. It took about 10 minutes.)
- Mental health scales (MH)(On Day 14 of the intervention, the researchers conducted the posttest (second test) at the participants' homes and the test content was the same as the first test. It took about 10 minutes.)
